My teams keeps on calling me useless each time enemy prioritizes me to snipe over my teammates (sometimes around 3 players try to snipe me with strats,arty or whatever), and even if i survive and leave all that reaclaim on our side, they still consider me the most useless teammate and ctrl+k.

I guess this: 6487652, around minute 36 specifically. Dual Gap. After a failed enemy strat snipe, they send in some more in small groups. White said he was fighting alone, you disagreed, he said smth like "All you did is survive", you said it's called tanking.

The game started at 16:06, went on for 46 minutes, so should have ended around 16:52. Your post was at 16:55. Given that, I think speed2s statement seems fitting, since I doubt you forgot the replay in 3 minutes (or 30, if we take your later statement into account).
